Secrets held for nearly 54 years regarding the assassination of former President John F. Kennedy could be less than a month away from being seen by the American public.

With an Oct. 26 deadline for to approve the release of documents pertaining to the Kennedy assassination, the Trump White House is being urged to let the people know what the FBI, CIA and other agencies have had to say about the Nov. 22, 1963, assassination of Kennedy.

“The American public deserves to know the facts, or at least they deserve to know what the government has kept hidden from them for all these years,” said Larry Sabato, director of the University of Virginia Center for Politics and author of a book about Kennedy.

“It’s long past the time to be forthcoming with this information,” he said.

Unless Trump steps in, the National Archives has until Oct. 26 to disclose the remaining files related to the Kennedy assassination.

In 1992, Congress passed a law mandating all assassination documents be released within 25 years, unless the president in office at the time of the scheduled release rules that doing so would be detrimental to intelligence, law enforcement, military operations or foreign relations.

More than 3,000 new documents could be released, in addition to 30,000 more that had been previously been available to the public with some information redacted.

The FBI will not say whether it has asked Trump to keep the files hidden.

A CIA spokeswoman only said it “continues to engage in the process to determine the appropriate next steps with respect to any previously-unreleased CIA information.”

Judge John Tunheim, who chaired the independent agency in the 1990s that made public many assassination records, said he thinks most of the major revelations have already made their way to the public.

Tunheim said the documents might show the details of the arrangements between the U.S. and Mexico for surveillance of those embassies.

However, Sabato thinks the files could reveal more about assassin Lee Harvey Oswald’s trip to Mexico City weeks before the killing. Oswald visited the Soviet and Cuban embassies during the trip.

The Warren Commission ruled that Oswald acted alone in killing Kennedy. That theory has been challenged several times over the years, but there has been no conclusive proof offered to dethrone the ruling as the official version of the assassination.
